So I'm sitting here having a pint of my first AG brew; it's Edwort's Stone Clone, brewed 6 meeks ago. I was soooo stoked on brewing this beer, but am dissapointed with the flavor. It's got what I'd describe for lack of a better term as a "metaly" aftertaste. I don't think it's contaminated, but.... It was brewed and Dry-hopped with Centenials, which I don't have a lot of experienc with. It's drinkable, but I'm about 2/3 though my first pint, and not sure I want to finish. My only thought is that it was the first time I used my keggle as a boil kettle, and maybe I didn't rinse it out well enough after cleaning it up from conversion?
